Occupation categories are based on the 1-digit level classification of respondent's job using the International Standard Classification of Occupations (ISCO-08). Standard error is abbreviated as s.e. Estimates exclude adults who could not be interviewed due to a language barrier or a cognitive or physical limitation. Detail may not sum to totals because of rounding.
